—Using a quaternionic reformulation of the threedimensional Electrical Impedance Equation, and a generalization of the Bers generating sets, as well as the Beltrami equation, we introduce a new class of exact solutions for the case when the conductivity is represented by a separable-variables function depending upon three spacial variables. Finally, we discuss the possible contribution of these...

—We analyze the structure of the general solution of the two-dimensional electrical impedance equation in analytic form using Taylor series in formal powers, for the case when the conductivity is a separable-variables function only once derivable, using a quaternionic reformulation that leads us to a special kind of Vekua equation. Finally, we broach its applications in the eld of electrical im...
